This is what I see if I go to the images and media page for a user and scroll through the media. Images still show up, but gifs and mp4s do not.

Sometimes it will show and play the gif/mp4, but then once I scroll far enough or it has loaded enough of them, they will stop loading altogether and show the above screenshot.
